JOSEF OTTMAR ZIEHER, OF GMIIND, GERMANY.

BRACELET.

SPECIFICATION forming part of Letters Patent No. 684,161, dated October8, 1901.

Application filed July 28. 1900. Serial No. 25,184. (No model.)

To all whom it may concern:

Be it known that I, Josnn OTTMAR ZIEHER, manufacturing jeweler, residingat '7 Kapuzinergasse, Gmiind, in the Kingdom of Wurtemberg,Germany, haveinvented certain new and useful Improvements in Bracelets, of which thefollowing is a full, clear, and exact description.

My invention relates to extensible or spring bracelets provided with apeculiar coupling for the loops or links, this coupling being-arrangedin such a manner that the bracelet may be easily contracted orelongated, as may be required. For this purpose I use a couplingconsisting of a framing adapted to receive diverging double wedges, towhich the loops or links are alternately connected. By this arrangementit is possible to make use of a variety of various ornaments, this factbeing of great importance in bracelets.

In order to reduce the friction of the sliding parts, it is preferableto employ a wedge of agate or glass.

In the accompanying drawings, Figure 1 is a diagrammatical view of thecoupling. Fig. 2 shows a front view of some of the loops or links of abracelet made according to this invention, said loops or links being intheir normal or unstretched position. Fig. 3 is a corresponding viewshowing the parts in their extended position. Fig. 4 is a side viewthereof. Fig. 5 and 6 are respectively front and side views, on a largerscale, of two loops or links coupled together. Fig. 7 is a crosssectionon the line 7 7 of Fig. 6. Fig. 8 shows an agate wedge removed from itsframing. Figs. 9 and 10 show modified designs of the wedge members.

As I have already stated, my bracelet is formed of a series of loopsorlinks and wedgelikepiecesalternatingwith oneanother. The wedge-likepieces constituting the aforesaid coupling are formed of divergingdouble wedges Z) Z), as shown in Fig. '1. The double wedge Z) Z: ismounted on or provided with an ornamental plate or framing c, andgrooves g are formed in its sides for the ends of the loops or links (Ito slide in. Each loop or link a has its ends nipping or pressingtightly against the sides of the wedge. The links a are coiled in such amanner that their ends e, sliding on the surfaces d of the Wedges,exercise a spring action upon them.

' The bracelet is composed alternately of double wedges and oflinks insuch a manner that two links constitute a common member between twodouble wedges, as clearly seen from Figs. 2 to 4:.

When the bracelet is extended, the ends of the loops or links are drawntoward the extremities of wedges and are thereby forced apart, so as toincrease the distaneebet-ween the members. On releasing the bracelet theresiliency causes the ends of the loops orlinks to slide toward the apexof the wedges, so contracting the bracelet.

In order to reduce the friction as far as 7 possible, the wedges arepreferably formed of agate or glass. A simple agate wedge n I haverepresented by Fig. 8.

The ends of the grooves g serve atthe same time as stops for the ends ofthe links, so as to limit the movement of the links or bracelet,respectively.

It is to be understood that the essential feature of my inventionconsists in the use of a double wedge, admitting ornaments of everykind, which could not be employed in the bracelets hitherto employed.

In the modifications represented by Figs. 9 and 10 the plates in are ofdifierent design from the plates 0 shown in the other views.

\Vhat I claim, and desire to secure by Letters Patent, is Y 1. In abracelet, the combination of a double wedge member of increasing widthtoward each extremity and open links having their ends engaging theopposite diverging sides of the wedges and arranged to slide along saidsides.

2. In a bracelet, the combination of a double wedge member of increasingwidth toward each extremity, open links having their ends engaging theopposite diverging sides of the wedges and arranged to slide along saidsides, and stops on the wedge member arranged to limit the said movementof the links.

In a bracelet, the combination of a double wedge member of increasingwidth toward each extremity, and open links having their ends engagingthe opposite diverging sides of the wedges and arranged to slide alongsaid sides, and means for guiding the said ends of the links.

4. In a bracelet, the combination of a donble wedge member of increasingwidth to ward each extremity, said wedges having grooves in saiddiverging sides, and open links having their ends engaging the walls ofsaid grooves and arranged to slide along said walls. j

5. In a bracelet, the combination of a double Wedge member, ofincreasing width toward each extremity, open links having their endsengaging the opposite diverging sides of the wedges and arranged toslide along said sides, and plates attached to the faces of saidwedge'member.

6. In a bracelet, the combination of adonble wedge member of increasingwidth toa hardened.bearing-surface for said links.

ward each extremity, and open links having 10' their ends engaging theopposite diverging: sides of the wedges and arranged to slide] alongsaid sides, said wedge member having 9 7. In a bracelet, thecombinationof a double wedge member of increasing Width to ward each extremity, andopen links having their ends engaging the opposite diverging sides ofthe wedges and arranged to slide along said sides, said wedges beingcomposed; of agate.
